“When Jerubbaal, as we read, was beating out wheat under an oak, he received a message from God in order that he might bring the people of God from the power of strangers into liberty. Nor is it a matter of wonder if he was chosen for grace, seeing that even then, being appointed under the shadow of the holy cross and of the adorable Wisdom in the predestined mystery of the future incarnation, he was bringing forth the visible grains of the fruitful corn from their hiding places and was [mystically] separating the elect of the saints from the refuse of the empty chaff. For these elect, as though trained with the rod of truth, laying aside the superfluities of the old man together with his deeds, are gathered in the church as in a winepress. For the church is the winepress of the eternal fountain, since from it wells forth the juice of the heavenly Vine.”

“And Gideon said to him, oh my Lord,.... Taking him not to be an angel, but some illustrious and eminent person: if the Lord be with us, why then is all this befallen us? all these troubles and calamities through the oppression of the Midianites; for he understood what was said to him in the salutation, respecting not himself personally and privately, but the people of Israel; and he could not tell how to reconcile the Lord's being with them, and yet suffering such sad things to befall them they groaned under: where be all his miracles which our fathers told us of, saying, did not the Lord bring us up from Egypt? when God was with his people, and brought them out of Egypt, he wrought miracles for them, whereby they were delivered out of their bondage; of this their fathers had assured them, but nothing of this kind was wrought for them now, and therefore there was no appearance of the Lord being with them, but all the contrary, as follows: but now the Lord has forsaken us, and delivered us into the hand of the Midianites; and there was good reason for it, because they had forsaken the Lord, and worshipped the gods of the Amorites.”

“Is. We should naturally translate, be with thee, if the answer of Gedeon did not shew (Calmet) that it is to be taken as an assertion, that the Lord was already reconciled to Israel, and had made choice of this valiant man to rescue his people from slavery, though he was not of the first nobility, ver. 15.”
